LG bottom Freezer french door error "ER 1F"

[chengsr]

Please help, LG LFX25960ST  I’m getting a error code “ER 1F” and the problem indicate to be a ice fan motor signal not detected.  The troubleshoot steps indicate the possibly of the fan motor or the main PCB.  The error resets every 20 min or so and it continue to make ice at a slower pace.  This indicate to me that the Ice fan motor is still blowing and perhaps the main PCB is becoming unstable and not detecting the motor’s presence.  My dilemma is to buy both parts around $150 or have a tech come onsite and do the repair. LG has a 7 years warranty on close system what every that means and I will have to pay for the labor.  Both parts are somewhat easy to access but LG will not reimburse me for the part directly.  Any suggestion?

Thanks for any direction.

Here are some info from the Service Manual and the 2 parts I found is

Icew Fan Motor                                    PCB Main
Number:  5209JA1044A    and                 EBR34917102

If you down to the fan or the board replace the fan first. Then replace the board (if needed) and you will have a new fan motor to go with it without paying a tech.

Thanks,

I've pull the ice fan unit out and the motor seems to spin freely and when I toggle the front door and put my hand on the ice blower vent, I can feel the cold air which indecate to me that the fan is blowing.  The ice fan unit only have 3 wires to the motor and I'm not sure what is triggering the error code on the main PCB.

Maybe one of the sensors is out of spec.

The circuit diagram is not the best from LG but there is only three wires going to the motor and I can not find another sensor that sense the ice fan unit.

a complet diagram.

I would replace that sensor before anything.

That's the problem, I can't find the sensor, what is monitoring the fan movement or the temperture inside the ice maker?

P.S. the ice maker is located on the top R/door not in the freezer.

Thanks for all your help.

On page 8 shows the defrost assembly, I too was wondering if that defrost assembly has that sensor in it and therefore it is not mentioned in the crappy manual. LOL. For such a machine they don't tell ya much do they?
